Retrieval tab options

Use the Retrieval tab to configure data retrieval options.

To configure data retrieval options

1. In the Retrieval mode list, select the retrieval mode that allows you to access the data stored in an AVEVA Historian in different ways.

   For more information on the retrieval options, see Understanding Retrieval Modes and Understanding Retrieval Options.

2. In the Query row limit list, select the maximum number of rows for the data retrieval to avoid excessively large result sets. For example, if you set a row limit of 200, the historian only returns the first 200 rows of a query’s results. The row limit applies to each query.
